4 Claims.

This invention relates to an instrument for emasculating animals and has for its primary object to. eiiect the emasculation bycrushing a section of the spermatic cord to render the same functionless and without cutting or injuring the pouch wherein the testiclesare contained. Thus, the primary aim and purpose of this invention is to effect apermanent sterilization of the animal in. a humane manner, without interfering with the free circulation of blood and without bruising the tissue of the pouch adjacent to the cord, so that. the animal. experiences little pain and discomfort and possibility of inflicting serious. injury is obviated.

Another object of this invention is to provide a castrating implement which will initially opcrate to close'upon the pouch and prevent withdrawal of the spermatic cord or preventimproper alignment or placement thereof with respect to the crushing means, the. crushing means. being centered upon opposite sides of the scrotum which overlies the spermatic cord and being subsequently actuated responsive to initial actuation of the means for holding the spermatic cord in proper position.

A meritorious feature of this invention resides in the provision of a stationary lever having. a laterally extending fixed jaw, a movable lever being pivotally associated with the stationary lever and being operatively associated with a plunger like member which is complementary to the upper portion of the fixed jaw for holding the spermatic cord in proper position for being operated upon, the plunger like member riding or moving relative to the fixed jaw and a movable jaw or crushing member, the latter being adapted for clamping coaction with the base of the fixed jaw for severing or crushing the spermatic cord. It is: to be noted that both of the operations, the initial operation of alignlllg the spermatic cord in the proper position, and the subsequent operation of crushing: the cord are successively carried out responsive to an uninterrupted movement of the movable lever relative to the stationary lever.

These and ancillary and supplemental objects and other meritorious features are attained by this invention, a preferred embodiment ofwhich is set forth in the following description and illustrated in the accompanying drawings, wherein:

Figure 1 is a side elevational view of the device constructed in accordance with the principles of the instant invention and illustrating the gripping jaws in a closed position;

Figure 2 is a top plan view of the instant invention, with a portion of the lever or handle broken away;

Figure 3 is a side elevational. view, partly in longitudinal section, the handle or lever portion beitlilg broken away and the side plates removed; an

Figure 4 is a sectional view taken on line 4-4 of Figure 1.

Referring now more particularly to the drawings, this invention generally designated by the reference character Hl includes a stationary lever or handle I2 havin a laterally disposed end extremity M defining a fixed jaw. The fixed jaw Is is formed with a straight crushing edge or face [6, the latter provided at its upper unattached edge with an offset section or abutment l8.

A. movable, handle or lever 20 is formed at its inner extremity with a pair of forwardly projecting parallel plates 22, riveted or otherwise secured as at 23 to the lever. The opposed parallel plates 22 are pivotally associated with the stationary lever [2 adjacent the fixed jaw by means of a transverse pivot pin. or bolt 24, the latter being detachably secured by a locking nut 26.

A pair of cover plates 23 andv 3i! shaped to conform to the outline of the stationary lever and fixed jaw are riveted as at 32 to the opposing sides of the jaw and lever. A movable jaw assembly 34 is slidably disposed between the plates 28 and and disposed in complementary relationship with the fixed jaw. It is to be here noted, with respect to Figure 4, that the edges of the cover plates 23' and 30 adjacent the face l6 of the fixed jaw are beveled as at 3b, the beveled edges 36 013 the plate and the straight edge of the fixed jaw defining in their associated placement a beveled face for. the fixed jaw.

The rear edges or rearward ends of the cover plates 23 and 39 are provided with arcuate recesses 38- to accommodate the periphery of the circular plates 32 during the pivotal movement of the plates about their pivot 24.

The movable jaw assembly 2d includes an upper section or plunger like member 40, which is formed with a blunt face 42 adapted for cooperative movement relative to the abutment IB, so as to engage upon opposite sides of the scrotum above the spermatic cord and prevent withdrawal of the cord and also enable the cord to be placed in the proper position to be operated upon until the crushing action of the instrument takes'place. Thus, a transverse pin. 44 is secured between the plates 28 and 38 and is adapted to travel in an elongated longitudinally disposed guide slot &6 formed in the plunger like member to limit the forward and rearward movement thereof relative to the abutment [8.

Means is provided for sliding the plunger like member relative to the fixed jaw and includes a somewhat elliptical recess 58 formed in the rear edge thereof to receive a dog disposed on a pair of lateral pins 52 and 54, the latter bein secured between the opposing plates 22.

As the plunger like member is moved forwardly, during the initial movement of the movable lever or handle relative to stationary lever a lower section of the movable jaw assembly or crushing member 56 is actuated by the further pivotal movement of the lever. The member 56 is formed with an appropriate crushing edge or face 58 adapted to abut against the face I6 of the fixed jaw. A pair of parallel upright extensions 60 and 62 are formed on the top or upper edge of the crushing member 58 to define a guide slot 64 positioned therebetween. A lug 66 depends integrally from the lower edge of the plunger like member and is adapted to freely slide within the recess between the extensions 60 and 62. A lateral extension 63 is formed adjacent the rear lower edge of the plunger like member and is adapted to abut against the extension 62.

With respect to Figure 3, it will be observed that when the handle moves relative to the stationary handle 12, the opposing plates 22 move about their pivot 24 and force the dog 58 into the recess 8 of the plunger like member. The plunger like member moves forwardly relative to the abutment I8 and the blunt face 42 thereof and the abutment l8 engage on opposing sides of the animals scrotum 76 above the spermatic cord 12 to prevent withdrawal thereof. Movement of the plunger like member through the cooperative abutment of the lugs or lateral extensions cooperatively carried by the plunger like member and the severing device results in a guided movement of the plunger-like member and the severing device. The severing face 58 of the lower section or severing device is moved into clamping engagement with the face of the fixed jaw and in association therewith applies a crushing or severing force to the spermatic cord by engagement of the dog with the rear surface of the device.

Thus, as the lever is moved upwardly the plunger-like member is moved forwardly relative to the fixed jaw by engagement thereof with the lever carried dog 50. As the dog clears the rear edge of the plunger member, the curved cam surface thereof engages the rear edge of the severing member and moves it toward the fixed It is to be noted that the two operations of the device, the positioning of the spermatic cord and the crushing thereof are successively performed by the device, during the uninterrupted and constant movement of the movable lever relative to the stationary lever. Thus, it can be appreciated that a constant and quick movement of the movable lever relative to the stationary lever will bring the working face of the movable jaw assembly into engagement of the working face of the fixed jaw in a manner to permanently crush the spermatic cord without injuring the tissue of the scrotum in the area surrounding the cord and without bruising or cutting the tissue to produce an open wound.

Of course, it is to be understood that the embodiment illustrated and described is by way of example only and certain changes and details in structure and other modifications may be carried out as coming within the scope of the appended claims.
